Speaking after the hearing, HSE inspector Simon Jones said: “Mr Khadka put his tenants and their children at a very real risk of death from the gas work he arranged at his rental property, done by someone who was not competent to do it safely.

“Landlords must ensure they only use Gas Safe Register installers to work on gas appliances at their tenanted properties.

“Further, landlord’s must ensure that gas appliances at their tenanted properties are checked for safety at least every 12 months.”
